Expect delays Wednesday morning if you use northbound I-5 in Tukwila.

Washington State Patrol says a crane overturned early Wednesday morning, blocking the left two lanes of I-5 at Southcenter Boulevard.

WSDOT closed all northbound lanes around 9:30 Wednesday morning while tow trucks flipped the crane over and removed it from the scene. Two right lanes of I-5 were opened about 45 minutes later, and a third lane was opened shortly after. As of 1:45 p.m., all but the HOV lane were open to traffic.

The closure caused lengthy backups from South King County into Seattle & Bellevue. At 10:20 a.m. there was still a three mile backup due to the wreck, according to WSDOT. Drivers were advised to avoid the area and use SR 99 & SR 167 as alternate routes.

A Class-C tow was called to the scene to help remove the crane.

WSP said around 100 gallons of hydraulic fluid was onboard and the EPA has been contacted.

Several agencies responded to the scene.

No injuries are reported.
